Understanding Oral PrEP Interest, Uptake, Persistence, and Experience of Use Among Heterosexual Men in Johannesburg, South Africa: An Exploratory Pilot Study.

South Africa's PrEP programming has primarily focused on men who have sex with men and other key populations through dedicated clinical and outreach services. However, data shows that the pool of men vulnerable to contracting HIV extends beyond this group, including men who have sex only with women and who do not identify as gay. The aim of this pilot study was to assess acceptability of PrEP among this subset of men who are at risk of HIV acquisition in South Africa and to describe the demographic and behavioral characteristics of male PrEP users as well as their experience of PrEP use. We employed a mixed-methods study design consisting of in-depth interviews and quantitative analysis of routine clinic data collected between September 2021 and February 2022 from 10 private health facilities. Men who enrolled in the study and initiated PrEP had low consistent condom use and nearly three quarters reported more than one sexual partner in the past three months. Despite minimal follow-up support, PrEP persistence was relatively high and similar to other populations. 57% of men returned for their 1-month visit, 40% returned for their 4-month visit, and 16% returned for their 7-month visit. The greatest barriers to ongoing use were the need to take a daily pill and low perceived HIV risk. To improve uptake and continuation, programs should increase awareness of PrEP, leverage trusted sources to build credibility, make access more convenient, and accommodate flexible use through event-driven PrEP.

RESUMEN: La programación de la PrEP en Sudáfrica se ha centrado principalmente en los hombres que tienen sexo con hombres a través de servicios clínicos y de servicio de alcance comunitario específicos. Sin embargo, los datos muestran que el grupo de hombres vulnerables a contraer el VIH se extiende más allá de este grupo, e incluye a hombres que sólo tienen relaciones sexuales con mujeres y que no se identifican como homosexuales. El objetivo de este estudio piloto fue evaluar la aceptabilidad de la PrEP en este subgrupo de hombres en riesgo de contraer el VIH en Sudáfrica y describir las características demográficas y de comportamiento de los usuarios masculinos de la PrEP, así como su experiencia con el uso de la PrEP. Se empleó un diseño de estudio de métodos mixtos que consistió en entrevistas a profundidad y análisis cuantitativos de datos clínicos rutinarios recolectados entre septiembre de 2021 y febrero de 2022, en 10 centros sanitarios privados. Los hombres que se inscribieron en el estudio e iniciaron la PrEP tenían un bajo uso consistente de condón y casi tres cuartas partes declararon haber tenido más de una pareja sexual en los últimos tres meses. A pesar de tener un apoyo de seguimiento mínimo, la continuidad de la PrEP fue relativamente alta y similar a la de otras poblaciones. El 57% de los hombres volvieron a su visita de 1 mes, el 40% volvieron a su visita de 4 meses y el 16% volvieron a su visita de 7 meses. Las mayores barreras para el uso continuo fueron la necesidad de tomar una pastilla diaria y la baja percepción del riesgo de VIH. Para mejorar la aceptación y la continuidad, los programas deben aumentar la conciencia sobre la PrEP, aprovechar las fuentes de confianza para aumentar la credibilidad, hacer que el acceso sea más cómodo y permitir un uso flexible mediante la PrEP a demanda.

Applying behavioural economics principles to increase demand for free HIV testing services at private doctor-led clinics in Johannesburg, South Africa: A randomised controlled trial.

Background: Expanding free HIV testing service (HTS) access to include private clinics could increase testing rates. A donor funded programme, GP Care Cell, offered free HIV testing at selected private doctor-led clinics but uptake was low. We investigated whether HTS demand creation materials that used behavioural economics principles could increase demand for HIV testing at these clinics. Methods: We conducted a randomised controlled trial in Johannesburg, South Africa (January-April 2022) distributing brochures promoting HTS to adults in five private doctor-led clinic catchment areas. Individuals were randomised to receive three brochure types: (1) "Standard of care" (SOC) advertising a free HIV test and ART; (2) "Healthy lifestyle screening" promoted free low-cost health screenings in addition to HTS; and (3) "Recipient of care voucher" leveraged loss aversion and the endowment effect by highlighting the monetary value of free HTS. The primary outcome was presenting at the clinic following exposure to the brochures. Logistic regression compared outcomes between arms. Results: Of the 12,129 brochures distributed, 658 were excluded because of errors or duplicates and 11,471 were analysed. About 59% of brochure recipients were male and 50,3% were aged 25-34 years. In total, 448 (3.9%) brochure recipients presented at the private doctor-led clinics of which 50.7% were males. There were no significant differences in clinic presentation between the healthy lifestyle screening and SOC arm (Adjusted Odds Ratio [AOR] 1.02; 95% CI 0.79-1.32), and similarly between the recipient of care voucher and SOC arm (AOR 1.08; 95% CI 0.84-1.39). Individuals were more likely to attend clinics that were centrally located with visible branding for HTS (AOR=5.30; 95% CI: 4.14-6.79). Conclusion: Brochures that used behavioural insights did not increase demand for HTS at private doctor-led clinics. However, consistent distribution of the brochures may have potential to increase HIV testing uptake at highly visible private doctor-led clinics.
